Benefits of technology

[0005]An aspect of the present invention provides an electrohydraulic pressure control device which has increased tolerance to shear loads and, at the same time, can be produced at low cost.

Problems solved by technology

Particularly when shear loads occur, however, leaks may occur in the seals owing to thin housing walls and little reinforcement.
The entry of liquid into the housing can lead to faults in subassemblies within the overall pressure control device and can cause failure of the corresponding vehicle brake system.

Embodiment Construction

[0030]In order to allow brief and simple description of the illustrative embodiments, identical elements are provided with identical reference signs, and in each case only the details essential to the invention are explained.

[0031]FIG. 1 shows an illustrative embodiment of the electrohydraulic pressure control device according to the invention for a vehicle brake system, e.g. for a two wheeled vehicle or a vehicle with more than two wheels, in section. Housing 3 of the electronic control unit 2 is sealed off essentially all round with respect to the environment by means of sealing material 5 in the zone of connection to the hydraulic control unit 1. Accordingly, sealing material 5 acts as a sealant and / or filler and can, in particular, furthermore be provided as an adhesive in order to effect or assist mechanical fixing of housing 3 on hydraulic unit 1.

[0032]Housing 3 furthermore surrounds circuit board 4 and support element 6. Electronic components 12, e.g. components for controlli...
